The Tableau Workbench (TWB) is a generic framework for building automated theorem provers for arbitrary propositional logics. The TWB has a small core that defines its general architecture, some extra machinery to specify tableau-based provers and an abstraction language for expressing tableau rules. This language allows users to “cut and paste” tableau rules from textbooks and to specify a sea...

The forming of low and high strength tailor welded steel sheets into preferred three-dimensional shapes by a homogeneous distribution plastic strain is highly difficult. In this work, the formability tailor-welded blanks prepared using laser welding (IS 513 CR2, IS CR3) tensile (AISI 304) were analyzed formation edge profile weld line movement was also examined. results showed decrease in chara...
